What the demo is
/demo is an anonymous chat interface pointed at our curated seed vault: 36 open-access peptides papers covering 14 topics (BPC-157, TB-500, GHK-Cu, semaglutide, tirzepatide, epitalon, MOTS-c, NAD+, selank, DSIP, cerebrolysin, PT-141, AOD-9604, pinealon).
You can ask anything that any one of those papers might cover. Answers are cited the same way as in a signed-in vault.
What it's for
- You want to see if our citation + refusal behaviour is real
- You want to share a sample question with someone before they sign up
- You want to test a question against papers you don't have access to
Limits
- 5 questions per IP per day. Resets at midnight UTC.
- Cloudflare Turnstile runs invisibly on each question to slow bot abuse.
- No chat history persists. Refresh the page and your session is gone.
What you see vs what a signed-in user sees
- Demo: answer text + citation titles + page numbers, but no clickable jump-to-source.
- Signed-in: full citation cards with the exact snippet and a link to open the source PDF.
When the daily limit hits
The 6th query returns a 429 with a "Sign up to keep chatting" CTA. The success response of the 5th query also shows "1 query left" so the limit isn't a surprise.
Where the limit lives
Atomically incremented via a Postgres RPC backed by a per-IP-per- day bucket key. So two simultaneous requests can't both pass the 5th-call boundary. The bucket key includes the date — so the reset is automatic at the day boundary, not a clock-driven cron job.
